This week on The Marketplace of Ideas, Colin Marshall talks to Edward Champion, who’s not only a book critic but the man behind two popular internet culture ventures, the blog Reluctant Habits and the interview podcast The Bat Segundo Show. An early adopter of podcasting technology, Champion has been conversing a sprawling variety of cultural figures since 2004, including the authors John Updike, William Vollmann and Bret Easton Ellis, filmmakers such as David Lynch and Atom Egoyan as well as guests from other spheres entirely, such as former United States Senator Mike Gravel.
